Abstract
The formation of an electron layer and the generation of an electron beam i n magnetron guns where secondary emission is triggered by nanosecond pulses are studied. In the guns with small cross sizes, hollow electron beams wit h an outer diameter of 3-6 mm are generated. The beam current is 1-2 A, and the cathode voltage is 5-7 kV. Results obtained indicate that the generati on of nanosecond beam-current pulses is a possibility. (C) 2001 MAIK "Nauka /Interperiodica".
